does the sensor make noise or just the base?

I would like to purchase this to help me catch a fearful cat, any noise will scare him. Will the sensor make noise or will it just make noise in the base so only i can hear it?
Asked by: mcnugget
The sensor flashes a green light in the sensor window when it is triggered and the batteries are good. The base unit makes noise and flashes its normally lit green light.

Do you have to buy the additional sensors? Im confused on if they come with the original purchase or you have to buy the up to 8 sensors separetly.

Asked by: Anonymous
The receiver comes with one sensor. If you want 8 sensors, you would have to buy 7 more SENSORS ONLY.

Motion Sensor with Wireless Motion Alert is rated 3.7 out of 5 by 253.
Rated 5 out of 5 by from Great product.....The best Purchased original version years ago with never a failure. Using two stations that have been in place for over 4 years without changing batteries. Just got new version to extend coverage. Also took one station and put it in my mailbox 1000 feet from the house. Works fantastic! Chamberlain should develop a separate mailbox alarm.

Rated 1 out of 5 by from Disappointed This is a good driveway sensor with one big flaw. I live in VT and it is only early November. This sensor is not made to work properly in cold weather. I have tried several different brands of batteries and it doesn't make a difference.

Rated 1 out of 5 by from Bought 3 and can barely hear the alert. I don't know what can be done to improve alarm strength. If you can't hear the alarm it's not much good

Rated 4 out of 5 by from Needs a blinking LED with reset The devise works great, as long as I'm within 20/30 feet of the alarm or even in the house. However, it only beeps once. ..which is fine. However, a circuit mod is needed for a simple led that blinks when alarm goes off, and continues to blink until reset. It is always easy to check the led occasionally to see if it went off. I use the system to monitor if the mailman placed an item in the box (which is about 150 feet away. This way, you may not hear the alarm, but at least you know that it went off.

The only complaint would be the high pitch of the alert sound, drives my 2 dogs crazy.

Rated 1 out of 5 by from The alert volume The alert volume is woefully inadequate to the point of making the system I bought plus extra sensor useless. They seem to sense things I want but if you do not hear alert what good is it.

It's range was good but the alert sound when a car or person set off it was so quiet even at max that the unit has to be next to you if wnt to hear it. It going back--unacceptable.
